These are my 1st practice shots, taken immediately after the lens arrived, with a GF2.
I took them in iAuto, and copied them directly from the card to the computer.
So there is no pp and no in camera user choices either.

It was easy to shoot full wide and full tel, but being new to the lens, I had to kind of guess at an intermediate range.

I will be taking the lens out this afternoon, this time on my G1 as a 2nd lens for the rugby (shot with the 45-200).
I also have two pens, so I will be trying it out on them eventually
